MIC49150

1.5A Low Voltage LDO Regulator

w/Dual Input Voltages

General Description

Features

The MIC49150 is a high-bandwidth, low-dropout, 1.5A volt-

age regulator ideal for powering core voltages of low-

power microprocessors. The MIC49150 implements a dual

supply conﬁguration allowing for very low output

impedance and very fast transient response.

• Input Voltage Range:

–

V_IN: 1.4V to 6.5V

_BIAS: 3.0V to 6.5V

• Stable with 1µF ceramic capacitor

• ±1% initial tolerance

The MIC49150 requires a bias input supply and a main

input supply, allowing for ultra-low input voltages on the

main supply rail. The input supply operates from 1.4V to

6.5V and the bias supply requires between 3V and 6.5V

for proper operation. The MIC49150 offers ﬁxed output

voltages from 0.9V to 1.8V and adjustable output voltages

down to 0.9V.

• Maximum dropout voltage (V_IN–V_OUT) of 500mV

over temperature

• Adjustable output voltage down to 0.9V

• Ultra fast transient response (Up to 10MHz bandwidth)

• Excellent line and load regulation speciﬁcations

• Logic controlled shutdown option

• Thermal shutdown and current limit protection

• Power MSOP-8 and S-Pak packages

The MIC49150 requires a minimum of output capacitance

for stability, working optimally with small ceramic

capacitors.

• Junction temperature range: –40°C to 125°C

The MIC49150 is available in an 8-pin power MSOP pack-

age and a 5-pin S-Pak. Its operating temperature range is

–40°C to +125°C.
